Why does WeChat voice have no sound and how to set it?

If you use a Huawei mobile phone, there is no sound when the WeChat voice message is played. If the volume adjustment is ineffective, please refer to the following scheme for troubleshooting:

1. Check whether the intelligent key device is plugged into the headphone jack.

If a intelligent key equipment (such as 360 intelligent key, Xiaomi intelligent key, ICBC U shield, etc. ) has been plugged into the mobile phone, please unplug the smart key device and try again.

2. Check whether the phone is connected to other audio devices.

If a Bluetooth device or other audio device is connected to the phone, please disconnect or remove the audio device and try again.

3. Check whether the mobile phone has a screen projection.

When a mobile phone projects a screen, the priority of sound output from high to low is: Bluetooth device, wired earphone, large screen, adapter and mobile phone. Please check whether the projection device is mute.

4. Check whether there is a new version of the application.

Please enter the Huawei application market to see if there is a new version of WeChat. Please try to upgrade your application to the latest version.

5. Still unable to solve

If the above methods fail to solve your problem, please back up your important data in advance (QQ, WeChat and other third-party applications need to be backed up separately), and bring the purchase voucher to Huawei customer service center for testing and processing.
